Nov 5 (Reuters) - Armis said on Wednesday it has raised

$435 million in its fundraising round, valuing the US-Israeli

cybersecurity firm at $6.1 billion, marking an over 45% increase

in just over a year.

Demand for digital threat prevention tools has surged amid

targeted attacks on critical electronic infrastructure used by

corporations and governments.

A series of cyberattacks has cost billions in monetary

losses and data leaks across the globe this year alone, with

lawmakers calling to make cyber-resilience a board-level

priority.

Armis' latest financing was led by the alternative

investments platform of Goldman Sachs ( GS ), with existing

investor CapitalG also participating in the round.

The San Francisco, California-based company said the funds

will be used to execute its three-year plan, involving reaching

$1 billion in annual recurring revenue and preparing for an

initial public offering.

Founded in 2016, Armis secures connected devices in real

time to protect against cyber threats, and serves more than 40%

of the Fortune 100 companies.
